This invention relates to the kind of machine for cutting green'corn from the cob shown in our Letters Patent of the United States No. 679,156, dated July 23, 1901,'and No. 787,585, dated April- 18, 1905, and the present inventionis directed to certain improvements in the details of construction of such machines whereby the operation of feeding the ears through the machine is'i1n proved and whereby the product of the machine is graded, the whole grains being separated from the scrapings, and considerable portions of grain heretofore wasted are saved. Y

The improvements are illustrated in the accompanying drawings and set forth in the following description and the features of novelty are finally claimed.

In said draWings- Figure 1 is a view in elevation of the right hand side of the machine with parts broken out. i

Figs. 2 and 3 are side and end views, respectively, of a feed roller used in the machine. I a

Fig. 4 is a side view on a larger scale of two links from the feed chain showing in end view the improved spur thereon.

Fig. 5 is a side view of one of the improved spurs referred to in the description of Fig. 4.

Fig. 6 is a view in elevation of the rear end of the machine.

Fig. 7 is a pl n vieW of the cob shaking screen installed at the rear end of the machine.

The construction of'the machine generally is like that shown in our former patents re ferred to and only so much of said machine is herein illustrated as is deemed useful for illustrating the improvements that constitute the subject of the present invention.

As in our former patents the present machine contains a frame 1, toothed feed chains 5, horizontal guides 7 and cutters 7 the vertical guides and cutters 8 and 8 the horizontal scrapers 11 and vertical scrapers 12, the feed rollers 13 on shafts 14 all, ex-

vcept the feed chain, being substantially as shown in the former patents referred to and to operate in substantially the same, way.

The main driving mechanism including the power shaft 17 may be the same as shown in our former patents.

In the present instance the spurs of the feed chain instead of being single pointed are double pointed and fiat in vertical arrangement or as shown at 5 in Figs. l'and 5 so as to engage the ear eircumferentially at two points. The advantage of such a spur is that it takesa firmer grip on the ear. The feed with. such a spur is therefore steadier and more reliable.

In the present construction we arrange upon the frame below .the'path of the ears a hopper .15 and divide that hopper by means of 'a partition 16 thatextends up through the path of the ear at the point where the cutting'has ended and thescraping begins. The partition is provided with an opening 16 to permit the'ears to pass through the partition from the feed rollers at the" forward side to the corresponding "rollers at the opposite side. The cuttings which are largely composed of practically whole grains of corn fall into the hopper at the forward SldG of the partitionand are discharged into a suitable receptacle, (not shown) placed below the discharge end of the first compartment or portion of the hopper. The scrapings likewise fall into the second or rear compartment or portion of the hopper and are caught in a suitable receptacle (not shown) placed below the end of said compartment.

Upon the rear end of the machine where the cobs discharge from the scrapers we mount a box-like frame 18 containing agrid or screen including parallel bars extending longitudinally with respect to the machine and held in position between the sides of the frames by means of bolts as at 20. The grid is held in a position to incline toward the rear so that cobs discharged thereon from the machine will in turn be discharged from the grid or screen. The box-like structure has in its forward end a cross bar 21 to receiVe a pivoting bolt 22 so that the box with its grid can be rocked thereon laterally. The grid is rocked during the operation of the machine by means of a pitman rod 23 actuated in one direction by an eccentric 24 on the main drive shaft 17 of the machine,

The actuation of the box in the opposite direction is effected, in the instance shown, by means of a sprlng 26 connected with the box and the table or frame of the machine. The cob issues from the cutters and scrapers upon the grid in a position parallel to the bars of the grid and small parts of grain that are carried by the cob through the machine are effectively shaken therefrom by the action of the bars of the grid or screen and fall upon the reversely inclined bottom of the box whence they descend into the rear compartment of the main hopper 15. The

saving of corn effected by theabove described device is quite considerable during a days operation.

In the present instance we employ rubber coveredrollers to feed the ears through the machine, such as shown in detail in Figs. 2 and 3, but such rollers do not constitute a subject of the present invention.

Changes in the form of the parts can be made without departing from the gist of the invention as claimed. 7

What We claim is:

1'. In a machine for cutting green corn from the cob including cutters for removing the grain, the combination with means for guiding the ears lengthwise to the cutters, of flexible members for feeding the ears through said guiding means, said flexible members each having a bifurcate-spur, the points of which engage the ear eircumferentially.

2. In a machine for cutting green corn from the cob, including cutters and scrapers thev latter arranged in rear of the cutters, the comblnation with the frame thereof, of a hopper arranged below the cutters and vscrapers said hopper having a partition to separate the cuttings from the; scrapings.

3. In a machine for cutting green corn from the cob, the combination with the frame thereof, of ahopper to receive the removed grains, said hopper having a partition for grading the removed portions of grain and said partition having an opening for the passage of the ear through the machine.

4. In combination with a machine for cutting green corn from the cob, having cut ters. and scrapers, means for feeding the ears longitudinally through the cutters and scrapers, a grid orscreento receive the cobs as they come from the scrapers, and means for laterally rocking said grid or screen to separate from the cobs thoseportions of the grain remaining on the cob after the scrap ing operation.

5. In combination with a machine for cut ting green corn from the cob, having cutters and scrapers, means for feeding the ears longitudinally through, the cutters and scrapers, an inclined grid or screen to receive the cobs as they come from the scrapers, and means for rocking said grid vor screen to separate from the cobsv those portions of the grain remaining on the cob after the scrap ing operation and to discharge the cob independently of said portions of grain.

6. In combination with a machine for cutting green corn from the cob having cutters and scrapers and means for feeding the ears longitudinally through the cutters and scrapers, independent receptacles for the cut tings and scrapings, an inclined grid or screen to receive the cobs as they come from the scrapers, means for rocking said screen laterally to separate from the cob those portions of the grain remaining on tllGQOlO after the sc'rapingoperation, and a frame in which said grid is mounted having a bottom inclined reversely to the screen for discharg ing said last named portions of graininto the scrapings receptacle.

7. In combination with a machine for cut ting green corn from the cob, -including car feeding devices, cutters and scrapers arranged in succession, a grid or screen to receive the cobs as they come from the scrapers, said grid comprising'a frame having bars parallel with the machine, and means for laterally rocking said grid to roll the ears laterally thereover to separate from the cobs those portions of the grain remaining on the cob after the scraping operation.

8. In combination with a machine for cutting green corn from the cob, including car feeding devices, cutters and scrapers arranged in succession a grid or screen'to rcceive the cobs as they come from the scrapers, said grid comprising a pivoted frame having bars parallel with the machine, and means for laterally rocking said grid to roll the ears laterally thereover to separate from the cobs those portions of the grain remaining on the cob after the scraping operation.
